[PATCH] D125310: [AArch64][RISCV][SelectionDAG] Support VECREDUCE_ADD mask operations

[Philip Reames via Phabricator via llvm-commits]

reames added a comment.

Please go ahead and land the new tests, and then rebase so that changes in codegen are visible in review.  Also, please rebase over the mentioned Aarch64 review.  The test diff there currently looks like a regression because you haven't stacked the changes which was confusing at first.

The submission comment needs improved to describe what this is actually doing.

The patch seems generally reasonable.  Once the above are done, should be an easy LGTM.
